Why is verification image so difficult to be read?

I tested and can not register even I see very good. some clients do not see in this way.
1. How to hide verification image and
2. How to put correct data as there is quoted:
Please enter the six letters or digits that appear in the image opposite.

Does it mean to put case sensitive letters in opposite order?

Some are very hard to read, but you can change it to a different system. If you really want to remove it, log into your admin cp, go to vbulletin option and select "human verification manager" and turn it off there, I personally think you're better off using reCatpcha, which involves creating an account on their site to get a code, but once that's done it works great, and is easy to read.

[Sebastiano Vassellatti]

No. Opposite also means "situated face to face", so it's just an adjective that refers to the position of the image in the page.

Uf, I see how vB lacks usability checking...I think also language issue is usability issue...nice suggestion to vB although I think great product and nice solutions (usability).
